Martinez was friends with the victim, and the two were shopping for cars when Martinez allegedly called Roschell and told him to rob the victim because he was carrying a significant amount of cash, prosecutors said in court today.

Roschell met up with Martinez and the victim, a 19-year-old man from Logan Square, and pulled the victim out of a car, prosecutors said.

Roschell fired a shot from a handgun but didn't hit anyone, prosecutors said. He then struck the victim in the head with the gun before a witness yelled that police were on their way, prompting Roschell and Martinez to run off, prosecutors said.

The victim suffered a broken arm and a cut to his head that required two staples to close, according to court documents. He was treated and released from Saints Mary and Elizabeth Medical Center.

Roschell, of the 3200 block of West Potomac Avenue, and Martinez, of the 5100 block of West Waveland Avenue, were both arrested Thursday night, according to court records.

Judge Edward Harmening set bail at $750,000 for Roschall, and $500,000 for Martinez.

Roschall is on parole for a juvenile case, and Martinez is on probation for a felony conviction, prosecutors said.
